I burned my first ignitor by following directions. "8+6 cyl. need 1.5 ohms resistance across the coil + to - " After I burned the piece, pertronix sent me another(6 day turn-around!). With the same instructions!!! I called their tech line and was told that 6 cyls. need 3 ohms. I added a Chrysler style ballast resistor, which brought my resistance up to 3.1 ohms- no more problems. I guess they have to use up all the old direction sheets before they print new ones.
